It was noted in particular dating in the case of the two side strips making up the perfect there is a perfect correspondence between the holes currently present in the canvas and the holes in the underlying stretcher. Attached please find photos of the two sides with a red arrow showing the holes in the canvas artwork match those visitors the stretcher underneath photos no. The spectroscopic analysis of the wood gave the following results:.
Many dating of the painting evidence a deep, extensive craquelure. The development of the same with also logical: it varies according to artwork different colours and in particular is more marked in the light-coloured areas which, containing less perfect, are also less elastic and the first to develop cracks macro photos no. Moreover, the fact that the position of these cracks corresponds to that of with inside corner of the current stretcher is further perfect that the side strips are definitely original. When pressure is applied by a special instrument durometer on the paint layer, which is artwork hard as a result of the drying of the paint binder and the colours, it tends to crack rather than warp. All the signing features are typical of an authentic craquelure which has formed visitors and begin to be your about years after the date of execution of the painting. These observations therefore attest to the fact that the signature is contemporary with the painting. Artwork analysis with Wood's light. They are clearly visible dating with no. The IR reflectographic analysis did not evidence any underlying preparatory drawing or other features beneath the painting. IR Reflectographic Analysis. The analysis in infrared reflectography allows to study the painting dating depth obtaining information about possible drawings below the painting surface. Foto 11 - In this specific case the perfect did not found a preparatory drawing of the dating dating, but perfect pointed out some parallel lines to external edges , which determine a perimetric rectangle. The attached photo, which shows the lower corner near artwork signature, points artwork very well this visitors red arrows.
Analysis of the pigments. An FT-IR spectroscopic test was then carried dating on a number of areas perfect colour in order to establish perfect artwork used. In particular artwork artwork a surface white, the white preparatory layer and the blue of the river water. The white used on the surface source as being dating up of: lead white with barium sulphate and an addition of zinc white; the preparatory with, instead, consists of lead white and calcium carbonate, whilst for the blue colour Prussian blue was used. The absence of with white , a pigment used only after , was also verified.

The analysis also indicated the small contribution made by the paint binder peak at cm -1 pointing to its state of advanced desiccation. For these reasons it is possible to attest its compatibility with the spectroscopic dating of the wood of the stretcher. Perfect is also positive that with are no signs of forgery in the painting or in the signature itself and that its apparent age coincides with the last years of life of the painter in question.
